Gravikord

The gravikord is a modern, 24 string, electric double bridge-harp invented by Robert Grawi in 1986, which is closely related to both the West African kora and the kalimba. It was designed to employ a separated double tonal array structure making it possible to play cross-rhythms in a polyrhythmic musical style in a modern electro-acoustic instrument. There is a similar instrument, also developed by Grawi, the gravi-kora, which is tuned identically to a traditional 21 string African kora.

Description

The gravikord is a new instrument developed on the basis of the West African kora. It is made of welded stainless steel tubing, with 24 nylon strings but no resonating gourd or skin. The bridge is made from a machined synthetic material with an integral piezo-electric sensor. Two handles located in elevation near the middle of the bridge allow holding the instrument. The bridge is curved to follow the arc of a strum from the hands which hold the shortened raised handles directly in the palms. A metal crossbar at the top of the bridge functions as a mechanical tone control and bridge stabilizer. The instrument connects to an amplifier like an electric guitar.
